Polyester silicone resins
View Patent ↗The present invention is directed to a group of silicone polyesters and a process for making them by reacting a specific carboxy silicone and a hydroxy silicone to make a surprisingly organic soluble, more biodegradable film forming resin. Additionally, the invention discloses a process for applying pigment to a substrate including skin, metal or glass, which comprises contacting the skin with a dispersion of pigment, a volatile solvent, and the resin disclosed.
1. A silicone polyester made by the esterification reaction of;
(a) a carboxy silicone compound conforming to the following structure:
wherein:
x is an integer ranging from 5 to 200;
with
b) a hydroxy silicone compound conforming to the following structure:
wherein:
y is an integer ranging from 5 to 200.
2. A polyester silicone of claim 1 wherein said esterification reaction is conducted at a temperature of between 150 and 200° C.
3. A polyester silicone of claim 1 wherein x is an integer ranging between 25 and 50.
4. A polyester silicone of claim 1 wherein y is an integer ranging from 25 to 50.
5. A polyester silicone of claim 1 wherein both x and y are independently integers ranging from 25 to 50.
6. A polyester silicone of claim 1 wherein x is an integer ranging between 10 and 20.
7. A polyester silicone of claim 1 wherein y is an integer ranging from 10 to 20.
8. A polyester silicone of claim 1 applied to skin, or hair.
9. A polyester silicone of claim 8 additionally containing pigment.
10. A silicone polyester conforming to the following structure;
wherein
A is
x is an integer ranging from 5 to 200;
B is:
wherein:
y is an integer ranging from 5 to 200;
z is an integer ranging from 50 to 5,000.
11. A polyester silicone of claim 10 wherein x is an integer ranging between 25 and 50.
12. A polyester silicone of claim 10 wherein y is an integer ranging from 25 to 50.
13. A polyester silicone of claim 10 wherein both x and y are independently integers ranging from 25 to 50.
14. A polyester silicone of claim 10 wherein x is an integer ranging between 10 and 20.
15. A polyester silicone of claim 10 wherein y is an integer ranging from 10 to 20.
